Abstract
Abstract A regulator for the window of a motor vehicle in which a rail rigidly connectable to a mobile window is movable in a primary path along a guide as driven by an actuator mechanism. The rail is coupled to the mechanism by way of two slides of which the first slide is coupled to said guide in order to translate the window along this guide in a manner allowing limited angular movement about the guide. The second slide is coupled to the first slide in a manner allowing translatory movement of the window in a secondary direction substantially perpendicular to the guide.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
A regulator for controlling the raising and lowering movement of a window within the door of a motor vehicle within a channel along one margin of a window opening of the vehicle, said regulator including a rigid guide affixed to said door adjacent said window opening and substantially parallel to said channel, a flexible drive cable linearly movable along a path generally parallel to said guide and externally thereof for raising and lowering said window, a first slide member secured to said window for movement therewith, a second slide member resiliently secured to said cable and tracked to said guide for movement therealong under control of said cable, said second slide member constrained to linear motion along said guide and means for connecting said first and second slide members to couple said members together for movement of said window in response to movement of the cable, said connecting means enabling a controlled amount of transverse movement between said slide members during raising and lowering movement of said window, means confining transverse movement to a direction generally transverse to the direction of said channel, and means coupling said second slide member to said guide to allow hinge motion of the member about the guide.
Claim 2
Dependent Claim
203 words
A regulator for controlling the raising and lowering movement of a window within the door of a motor vehicle within a channel along one margin of a window opening of the vehicle, said regulator including a rigid guide affixed to said door adjacent said window opening and substantially parallel to said channel, a flexible drive cable linearly movable along a path generally parallel to said guide and externally thereof for raising and lowering said window, a first slide member secured to said window for movement therewith, a second slide member resiliently secured to said cable and tracked to said guide for movement therealong under control of said cable, said second slide member constrained to linear motion along said guide and means for connecting said first and second slide members to couple said members together for movement of said window in response to movement of the cable, said connecting means enabling a controlled amount of transverse movement between said slide members during raising and lowering movement of said window, means confining transverse movement to a direction generally transverse to the direction of said channel, and means coupling said second slide member to said guide to allow hinge motion of the member about the guide.
Claim 3
Dependent Claim
52 words
A regulator as claimed in claim 1, in which there are two slide blocks apart along said guide with a similarly shaped slot in each of said blocks, and in which said slot has one section closely confined about said guide to act as a hinge for said slide block angular movement.
Claim 4
Dependent Claim
31 words
A regulator as claimed in claim 1, in which said connecting means comprises a lost motion connection between said slide blocks including a transversely elongated slot in one of said blocks.
Claim 5
Dependent Claim
28 words
A regulator as claimed in claim 1, in which the coupling of said cable to said second block comprises a spring biased connection for maintaining said cable taut.
Claim 6
Dependent Claim
78 words
A regulator as claimed in claim 1, in which said guide comprises a generally L shaped bracket, and in which there is at least one slide block on said second slide member for said tracking to said guide, said tracking comprising a slot in said slide block for receiving the said guide, said slot including a section oversized considerably greater than the thickness of said guide to allow angular movement between said second slide member and said guide.
Claim 7
Dependent Claim
36 words
A regulator as claimed in claim 5, in which said slot in said slide block includes convex walls disposed about said guide to define said hinge coupling about an axis corresponding to that of said guide.
